Intel Core i9-9920X vs Intel Core i9-9940X

Core i9-9920X vs Core i9-9940X comparison

In our benchmarks, the Core i9-9940X beats the Core i9-9920X in overall performance. Despite this, the Core i9-9920X has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i9-9940X has slightly more cores with 14 cores compared to the Core i9-9920X that has 12 cores. It also has more threads than the Core i9-9920X. These CPUs have different clock speeds. Indeed, the Core i9-9920X has a slightly higher clock speed compared to the Core i9-9940X. In addition, both chips have the same turbo speed. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i9-9920X has more threads than cores. Each physical core is split into multiple threads.
